▶ Connect the PWM signal cable [2] of the pump to the 2-pin plug.
▶ Guide both cables through the strain relief.
▶ Connect the pump terminal unit: fold the pump terminal unit up and
press horizontally until it snaps into place.
Without pump assembly:
When using pump types other than those available from Bosch as
accessories, the PWM signal cannot be used. The PWM connection in the
pump terminal unit is then not used. On/Off operation applies for these
pumps.
▶ Connect the 230 V mains cable of the pump to the 3-pin plug [1].
